8 Gaims. (Cl. 72-16) This invention relates to prefabricated houses, and more particularly to building sections forming the exterior walls of such houses, and to a method of joining such sections together.

One object of the invention is to provide building sec tions of the type described comprising a frame work which is covered by sheet metal on the outside.

Another object of the invention is to provide a building section having an exterior sheet metal protection supported by a layer of masonry, preferably comprising a light concrete of special composition.

Still another object of the invention is to provide building sections of the type indicated which may simply and readily be joined together to form a wall.

A still further object of this invention is to provide a building section of the kind referred to in which insulating material, such as insulation blankets, may be mounted in place as a step in the manufacture of the sections.

Another object of the invention is tov provide a building section having an exterior sheet metal cover which is pro-formed to provide an appealing and decorative pattern.

A further object of the invention isto provide a building section that is simple in design, inexpensive and uncomplicated to manufacture, and economical in maintenance.

This invention also has for its. object to provide a method whereby building sections of the type referred to are secured to each other by fastening means in such a way as to provide confined open spaces between members of two adjoining sections, said spaces then being filled by pouring concrete into the same.

Other objects and advantages of the invention will be apparent from the following description of an embodiment thereof illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of a building section according to the invention, with portions broken away to show certain details of construction;

Fig. 2 shows a vertical cross-section through a building section with; interior wallboard or plasterboard in place;

Fig; 3 shows a horizontal cross-section of the structure at one of the vertical studs;

Fig. 4 shows a perspective view of a detail of they concrete reinforcing structure;

Fig. 5 is a horizontal cross-sectional view of a corner joint and a plain joint between adjacent building sections;

Fig. 5A is an enlarged view, broken away, of the joint between sections shown in Fig. 5; and

Figs. 6, 7, and 8 show diagrammatically three different examples of general design of the building sections.

In the embodiment shown, each section consists of a frame comprising a bottom piece 10, a top piece 11, and

. a, number of studs 12, i3, 14, and 15, joined together in any suitable manner. The bottom and top members It and 11 are somewhat wider than the vertical members 12, 13, 14, 15 which are mounted flush with one edge of the horizontal members 10, 11.

Sheet metal strips 16 are secured to the studs 12. and 15, and other sheet metal strips 17 are similarly secured to the studs 13 and 14, all on the exterior edge of said studs, One of the strips 16 is shown in a perspective view in Fig. 4, from which it will be apparent that the States Patent O strip. is bent longitudinally at 18 and provided with flaps; S0

19 and 20 which are bent alternately outwards and in- 2,704,935 Ce Patentedv Mar. 29, 1955 wards. The strips 17 are of similar construction but provided with two longitudinal bends and two rows of flaps 111 2;), one at each longitudinal edge, as clearly shown in A wire 21 is strung up on the flaps 19 between each pair of studs, as between the studs 12 and 13, for instance, as indicated in the drawings. These wires serve as reinforcements for the layer of concrete, or similar material, to be described below.

A piece of sheet metal 22, large enough to cover the entire section, is secured to the exterior side of the frame. It is supported by the horizontal members 10, 11 directly, as indicated in Fig. 2, while spacer tubes 23 are inserted between the sheet metal and the studs, as indicated in Figs. 3 and 5. To secure the sheet metal to the frame wood screws 24 may be used, as indicated in Fig. 3, or bolts 25 and nuts 26, as shown in Fig. 5. The sheet metal may be plain, but is preferably provided with longitudinal ridges 27, as indicated in the drawings. The sheet metal is preferably a material that is resistant to rust and corrosion, such as aluminum, aluminum alloy, or stainless steel.

Against the interior side of the sheet metal a layer of concrete 28 is poured. This is preferably done with the frame in a horizontal position, in which case no special form is needed. except at the edges, the concrete being poured directly upon the sheet metal to a thickness that may be varied as desired. Thus, although this layer is shown in the drawings to extend to the outer edge of the studs 12, 13, 14, 15, it may be increased to cover part of the sides of said studs, if desired. Of course, the strips 16, i7 and the wires 21, will be imbedded in this concrete layer Where they Will serve as reinforcement. A highly suitable material for this concrete layer is a. concrete-asphalt emulsion prepared by using vermiculite instead of sand.

At a distance from the interior side of the concrete layer, insulation blankets 29 may be secured to the frame. This can be done before the erection of the sections, as indicated in Fig, 1 where only a small space of air is left between the concrete and the insulation, as shown in Figs. 2 and 3. However, it may also be done, or completed, after erection, which would be necessary in the case illustrated in Fig. 5 since in this case bolts, 30,v 31

i with nuts 32 and 33, respectively, for joining adjacent sections together are provided between the two layers.

These joints between adjacent sections are exemplified in Fig. 5 which. shows one joint between two sections of the same Wall, and one corner joint. The plain joint is accomplished by placing the two sections with adjacent edges against each other and tightening the nuts 32 on the bolts 3t) after placing a grooved strip 34 in such a position as to allow the edges of the sheet metal covers 22'to enter the longitudinal grooves of said strip. 34. In same cases these strips 34 may be slid down between the edges of the sheet metal pieces 22 from the top after joining the sections. The width of the sheet metal 22 is somewhat less than the frame to allow space for said strip 34. In pouring the concrete layers 28 the edges thereof are preferably formed with indentations, as indicated at 35, and upon mounting the strips 34in place, the space between adjacentv edges of the concrete layers 23 is filled with material of the same kind poured in from the top which forms a uniting concrete strip 36 between the two edges.

The corner joints are formedv by securing the flanges of short pieces of angle irons 37 to adjacent frame members by means of the bolts 31 and nuts 33. Between said angle irons 3'7, wooden members 38 of triangular cross-section may be secured to the two frames, if desired. A pre-formed corner piece of sheet metal 39 is then placed in overlapping position to, the sheet metal 28 of the two sections and secured, together therewith, by means of the bolts 25 and nuts 26,, whereupon the space within said sheet metal corner piece 39 is filled in from above with concrete mixture 49 of the same kind as the material 28. Wallboards 44 or any other type of interior wall material may be applied to the inside of the frames.

Building sections containing windows 41 and 42 and doors 43 are made in a similarway, although the. frames 3 are somewhat different in that the intermediate studs 13 and 14 will have to be cut and held together by transverse members in a manner well known in the art. Also, additional vertical members may have to be inserted between said transverse members, as is equally well known in the art.

It will be noted that this invention provides a wall structure in which the durable and tight exterior sheet metal cover is supported throughout by a continuous layer of concrete that adheres to the sheet metal completely, following any pattern that may be imparted to said sheet metal. In other words, there is a solid and Uniform support for the sheet metal throughout.

Furthermore, since the concrete mixture is poured into place, it can be made to follow the contour of window and door openings completely, regardless of the size or shape of said openings, thus dispensing with the need of a variety of sizes and shapes of prefabricated concrete blocks or bricks, and with the necessity of chopping and shaping such blocks. By using vermiculite in the concrete the building sections can be made extremely light.

It is to be understood that modifications of the abovedescribed embodiments of the invention may be made within the limits of the appended claims and without departing from the spirit of the invention.
